Angelonia plant named ‘Cas Wite 09’

ABSTRACT

A new  Angelonia  plant named ‘Cas Wite09,’ particularly distinguished by the clear white flower color, slightly upright and semi-trailing habit with dense foliage and branching, exceptional heat tolerance, and good vigor.

Latin name of the genus and species of the plant claimed: Angeloniaangustifolia.

Varietal denomination: ‘Cas Wite09’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Angelonia, botanically known asAngelonia angustifolia, and hereinafter referred to by the variety name‘Cas Wite09.’

‘Cas Wite09’ is a product of a planned breeding program. The newcultivar ‘Cas Wite09’ has a clear white flower color, slightly uprightand semi-trailing habit with dense foliage and branching, exceptionalheat tolerance, and good vigor.

‘Cas Wite09’ originated from a hybridization in a controlled breedingprogram in Gilroy, Calif. USA. The female parent was an unpatentedhybrid seedling identified as ‘433-1’ with lavender and white color.‘433-1’ has a lighter foliage color and is more upright in habit than‘Cas Wite09.’

The male parent of ‘Cas Wite09’ was an unpatented hybrid seedlingidentified as ‘407-3’ with white color. ‘407-3’ has a lighter foliagecolor, is more prostate in habit, and has smaller more cupped flowersthan ‘Cas Wite09.’

‘Cas Wite09’ was selected as one flowering plant within the progeny ofthe stated cross in 2006 in a controlled environment in Gilroy, Calif.USA.

The first act of asexual reproduction of ‘Cas Wite09’ was accomplishedwhen vegetative cuttings were taken from the initial selection in June2006. The pollination took place in September 2003 and the seed sowingin March 2006, all in a controlled environment in Gilroy, Calif. USA.

Horticultural examination of plants grown from cuttings of the plantinitiated in June 2006 in Gilroy, Calif. USA, and continuing thereafter,has demonstrated that the combination of characteristics as hereindisclosed for ‘Cas Wite09’ are firmly fixed and are retained throughsuccessive generations of asexual reproduction.

‘Cas Wite09’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada onDec. 24, 2007. ‘Cas Wite09’ has not been made publicly available morethan one year prior to the filing of this application.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Cas Wite09’ with colors being as true as possiblewith an illustration of this type. The photographic drawing shows aflowering potted plant of the new variety and a close-up of the flowers.Both photographs were taken in the spring of 2008 in Gilroy, Calif. USA.Both were grown in Gilroy, Calif. USA and were approximately 3–4 monthsold.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Gilroy, Calif. USA, in April 2008 onplants that were growing in gallon pots. Culture of these plants startedin about January in a greenhouse. The plant was about 3 months old.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describeplants grown in a greenhouse in Gilroy, Calif. USA. The following traitshave been repeatedly observed and are determined to be basiccharacteristics of the new variety. The combination of thesecharacteristics distinguishes this Angelonia as a new and distinctvariety.
